One time I worked helping people with "Internet"... everything from modem power-cycling to email set-up to driver configuration to listening to people yell before transferring them to billing... anyways... the call script had some kind of "are there any other questions?" thing we had to say before the end of each call and we had to keep saying it until they said no so sometimes the customers would get clever and start asking "funny" questions like:
"What are tomorrows Lottery numbers?" (If I knew that do you think I would have come to work today?)
"What's your credit card number?" (I'm not authorized to divulge personal information to customers.)
"What's you favorite Robert Frost poem?" (Stopping By Woods on A Snowy Evening)
... or the time the customer asked "What's Pi to 10 places?" and I totally said "3.1425926535" without skipping a beat.
